karyotype

karyotype

the chromosomal constitution of the cell nucleus; by extension, the photomicrograph of chromosomes arranged. See also illustration at chromosome.

Preparation of a karyotype. From Mueller and Young, 2001.

kar·y·o·type

(kar'ē-ō-tīp),

The chromosome characteristics of an individual cell or of a cell line arranged in descending order of size and according to the position of the centromere. Usually presented as a systematized array of metaphase chromosomes from a photomicrograph of a single cell nucleus.

karyotype

/karyo·type/ (-tīp″) the chromosomal constitution of the cell nucleus; by extension, the photomicrograph of chromosomes arranged according to the Denver classification.

karyotype

(kăr′ē-ə-tīp′)

n.

1. The characterization of the chromosomal complement of an individual or a species, including number, form, and size of the chromosomes.

2. A photomicrograph of chromosomes arranged according to a standard classification.

tr.v.karyo·typed, karyo·typing, karyo·types

To classify and array (the chromosome complement of an organism or a species) according to the arrangement, number, size, shape, or other characteristics of the chromosomes.

kar′y·o·typ′ic(-tĭp′ĭk), kar′y·o·typ′i·cal adj.

karyotype

[ker′ē·ətīp′]

Etymology: Gk, karyon + typos, mark

1 the number, form, size, and arrangement within the nucleus of the somatic chromosomes of an individual or species, as determined by a microphotograph taken during metaphase of mitosis.

2 a diagrammatic representation of the chromosome complement of an individual or species, in which the chromosomes are arranged in pairs in descending order of size and according to the position of the centromere. See also chromosome, Denver classification, idiogram. karyotypic,adj.

kar·y·o·type

(kar'ē-ō-tīp)

The chromosome characteristics of an individual cell or of a cell line, usually presented as a systematized array of metaphase chromosomes from a photomicrograph of a single cell nucleus arranged in pairs in descending order of size and according to the position of the centromere. Synonym(s): idiogram (1) .

[karyo- + G. typos, model]

karyotype

1. The individual chromosomal complement of a person or species. The genome.

2. The CHROMOSOMES of an individual set out in a standard pattern and obtained from a photomicrograph taken in METAPHASE that has been edited with software so that the separate chromosomes are arranged in numerical order. This is done for the diagnosis of chromosomal disorders, as in prenatal detection of fetal abnormality.

karyotype

the CHROMOSOME complement of a cell or organism, characterized by the number, size and configuration of the chromosomes as seen during metaphase of MITOSIS.

Karyotype

A standard arrangement of photographic or computer-generated images of chromosome pairs from a cell in ascending numerical order, from largest to smallest.

(kar'ē-ō-tīp)

The chromosome characteristics of an individual cell or of a cell line, usually presented as a systematized array of metaphase chromosomes from a photomicrograph of a single cell nucleus arranged in pairs in descending order of size and according to the position of the centromere. Synonym(s): idiogram (1) .

[karyo- + G. typos, model]
